INSTALLGRUB(8) Maintenance Commands and Procedures INSTALLGRUB(8)
installgrub - install GRUB in a disk partition or a floppy
/sbin/installgrub [-fm] stage1 stage2 raw-device
The installgrub command is an x86-only program. GRUB stands for GRand
Unified Bootloader.
installgrub installs GRUB stage 1 and stage 2 files on the boot area
of a disk partition. If you specify the -m option, installgrub
installs the stage 1 file on the master boot sector of the disk.
The installgrub command accepts the following options:
-f
Suppresses interaction when overwriting the master boot sector.
-m
Installs GRUB stage1 on the master boot sector interactively.
You must use this option if Solaris is installed on an extended
FDISK or an EFI/GPT partition.
The installgrub command accepts the following operands:
stage1
The name of the GRUB stage 1 file.
stage2
The name of the GRUB stage 2 file.
raw-device
The name of the device onto which GRUB code is to be
installed. It must be a character device that is
readable and writable. For disk devices, specify the
slice where the GRUB menu file is located. (For Solaris
it is the root slice.) For a floppy disk, it is
/dev/rdiskette.
The following command installs GRUB on a system where the root slice
is c0d0s0:
example# /sbin/installgrub /boot/grub/stage1 \
/boot/grub/stage2 /dev/rdsk/c0d0s0
The following command installs GRUB on a formatted floppy:
example# mount -F pcfs /dev/diskette /mnt
# mkdir -p /mnt/boot/grub
# cp /boot/grub/* /mnt/boot/grub
# umount /mnt
# cd /boot/grub
# /sbin/installgrub stage1 stage2 /dev/rdiskette
/boot/grub
Directory where GRUB files reside.

Installing GRUB on the master boot sector (-m option) overrides any
boot manager currently installed on the machine. The system will
always boot the GRUB in the Solaris partition regardless of which
fdisk partition is active.

NAME
installgrub - install GRUB in a disk partition or a floppy
SYNOPSIS
/sbin/installgrub [-fm] stage1 stage2 raw-device
DESCRIPTION
The installgrub command is an x86-only program. GRUB stands for GRand
Unified Bootloader.
installgrub installs GRUB stage 1 and stage 2 files on the boot area
of a disk partition. If you specify the -m option, installgrub
installs the stage 1 file on the master boot sector of the disk.
OPTIONS
The installgrub command accepts the following options:
-f
Suppresses interaction when overwriting the master boot sector.
-m
Installs GRUB stage1 on the master boot sector interactively.
You must use this option if Solaris is installed on an extended
FDISK or an EFI/GPT partition.
OPERANDS
The installgrub command accepts the following operands:
stage1
The name of the GRUB stage 1 file.
stage2
The name of the GRUB stage 2 file.
raw-device
The name of the device onto which GRUB code is to be
installed. It must be a character device that is
readable and writable. For disk devices, specify the
slice where the GRUB menu file is located. (For Solaris
it is the root slice.) For a floppy disk, it is
/dev/rdiskette.
EXAMPLES
Example 1: Installing GRUB on a Hard Disk Slice
The following command installs GRUB on a system where the root slice
is c0d0s0:
example# /sbin/installgrub /boot/grub/stage1 \
/boot/grub/stage2 /dev/rdsk/c0d0s0
Example 2: Installing GRUB on a Floppy
The following command installs GRUB on a formatted floppy:
example# mount -F pcfs /dev/diskette /mnt
# mkdir -p /mnt/boot/grub
# cp /boot/grub/* /mnt/boot/grub
# umount /mnt
# cd /boot/grub
# /sbin/installgrub stage1 stage2 /dev/rdiskette
FILES
/boot/grub
Directory where GRUB files reside.

boot manager currently installed on the machine. The system will
always boot the GRUB in the Solaris partition regardless of which
fdisk partition is active.
